With the emergence of cloud and social networking sites, information security has become a major challenge. Images are the most searched, uploaded and shared data in multimedia. However, because of the data size and high redundancy among the raw pixels of a digital image, traditional encryption algorithms might not be suitable for image encryption. In this paper, we propose a novel color image encryption algorithm using a three dimensional chaotic cat map and a programmable complemented maximum length CA(PC-MLCA). The proposed method performs a thorough experiment test through detailed analysis to demonstrate the high security and reliability of the new image encryption system.
